A digital delay line (or simply delay line, also called delay filter) is a discrete element in a digital filter, which allows a signal to be delayed by a number of samples. Delay lines are commonly used to delay audio signals feeding loudspeakers to compensate for the speed of sound in air, and to align video signals with accompanying audio ...
The delay line may be realized with a physical delay line (such as an LC network or a transmission line). In contrast to a Phase-shift oscillator in which LC components are lumped, the capacitances and inductances are distributed through the length of the delay line. A ring oscillator uses a delay line formed from the gate delay of a cascade of ...
One example of an analog delay line is a bucket-brigade device. [1] Other types of delay line include acoustic (usually ultrasonic), magnetostrictive, and surface acoustic wave devices. A series of resistor–capacitor circuits (RC circuits) can be cascaded to form a delay. A long transmission line can also provide a delay element. The delay ...
When their signal is reflected back, it is mixed with the inverted signal from the delay line, which cancels out the echo. This allowed both modems to use the full spectrum available, doubling the possible speed. Echo cancellation is also applied by many telcos to the line itself and can cause data corruption rather than improving the signal.
Delay-line memory is a form of computer memory, mostly obsolete, that was used on some of the earliest digital computers, and is reappearing in the form of optical delay lines. Like many modern forms of electronic computer memory, delay-line memory was a refreshable memory , but as opposed to modern random-access memory , delay-line memory was ...
A digital delay generator (also known as digital-to-time converter) is a piece of electronic test equipment that provides precise delays for triggering, syncing, delaying, and gating events. These generators are used in many experiments, controls, and processes where electronic timing of a single event or multiple events to a standard timing ...
Delay line may refer to: . Propagation delay, the length of time taken for something to reach its destination; Analog delay line, used to delay a signal; Bi-directional delay line, a numerical analysis technique used in computer simulation for solving ordinary differential equations by converting them to hyperbolic equations
The Malaysian Aviation Commission (Malay: Suruhanjaya Penerbangan Malaysia; officially abbreviated as MAVCOM) is a regulatory body for the aviation industry in Malaysia under the Ministry of Transport. Established in 2016, it entrusted to regulate the economic and consumer issues of the civil aviation sector. [1] [2]
